2. Casting alloys
2.1 Pure copper
There is only one grade of pure copper specified in the standard NF EN 1982 . No composition is specified for this grade, which only has to meet minimum mechanical and electrical conductivity requirements. The difficulty in producing parts in pure copper is the high reactivity of liquid copper with oxygen and hydrogen, which leads to the phenomenon of roaching (Fig.
